Question

In which of the following cases, the object reaches the ground first?

• A. Case 1
• B. Case 2
• C. Case 3
• D. Case 2 and Case 3

Answer 1

The correct option is B Case 2

Rolling friction is less as compared to sliding friction.
In case 2, as the object placed on the wedge would be rolling on it, the friction will be minimum in this case, thus the object would be moving faster. Hence, object 2 will reach the ground first.
